NIPPER-TUBE.

T 0 all whom it may concern:

Be it known thatI, WILLIAM A. BERRY, a citizen of the United States, residing at Xenia, in the county of Greene and State of Ohio, have invented a new and useful NipperTube, of which the following is a speciiication.

The improved nipper tube for which I claim invention and improvement, is a part of the nipper stand which in turn is attached to most of the spinner machines now in common use in the manufacture of twines and threads of all materials.

The object of the improved nipper tube is to produce a round, smooth, strong and compact thread, after having passed, as a sliver, through the said improved nipper tube, the use of said improved nipper tube dispensing with the use of the more expensive nipper machine now in general use. I attain this object by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the improvement with the parts in normal position; Fig. 2 is an end elevation of the same; Fig. 3 is a side view of the tube members detached; Fig. 4 is a plan view of the same members separated, and Fig. 5 is a front end view of the parts shown in Fig. 3.

Similar letters refer to similar parts throughout the several views.

The sliver passes into the improved nipper tube at a, through the improved tube, emerging at c a round smooth and compact thread.

The improvement which I claim to have efi'ected in the spinner process, through the said. improved nipper tube, consists in narrowing and diminishing the dimension, diameter and circumference of the said nipper tube, again widening out to original dimension, change of said dimension commencing after entering the tube, a, to I), I) being about one fifth the length of the tube from ct, continuing to one half the length of said tube as demonstrated. in Figs. 3 and 4. The change of said dimension, at both ends, is gradual, and smooth, approaching gently the full dimension at either end. As the process of spinning progresses, with the use of the said improved nipper tube, a rounder, smoother, stronger and more compact thread is pro- Speeification of Letters Patent.

duced than heretofore, when the nipper tube, throughout its entire length, was of the same dimension, diameter and circumference and without the change noted in Fig. 4, of the improved nipper tube.

The said improved. nipper tube may be cast in metal or other hard substance, from pattern, or cut, as to all of which substances the improvement applies.

As the sliver emerges at c, with the use of the improved nipper tube the spinning process is complete, without the use of the nipper machine now in common use, which is a more complex and expensive affair.

The nipper tube consists of two parts 10 and. 11, the former being located in a support 12 having an ear 13. The part 11 is placed above the part 10, and is guided by said support 12 for vertical movements toward and from the lower member 10. An arm 14, having an adjustable weight 15, is pivoted to said ear 1S, and has bearing contact with the upper side of member 11 whereby this member may be resiliently held to its work or readily removed for the purpose of introduction of the work. To facilitate such removal, after the arm 14 has been withdrawn therefrom, the member 1.]. is provided with a projection 11 which may be grasped by the hand of the operative.

longer than the ordinary forms of nipper tubes, it is highly desirable that the member 11 be readily removable for inspection purposes and insertion of the work, whereby threading of the work into the bore in starting is avoided.

I claim:

1. The combination with a support, of a two part nipper tube mounted therein, one of said parts being stationary and the other being vertically movable with respect thereto and readily removable therefrom, said tube parts being longitudinally grooved to form a bore having flaring ends, and a weighted arm pivoted to said support and cooperating with said movable member to hold it in proper working position.

2. The combination with a support having an ear, of a tube member located in said support and stationary relative thereto, a mov- The tube mem-. bers 10 and 11 being comparatively much able tube member guided in said support and and whereby upon withdrawal of the arm cooperating with the upper face of the afore the said upper movable member may be said tube member, said members being readily removed, substantially as set forth. 10 grooved to form a tapered bore, and a WVILLIAM A.
